WAGON-SPRING.

Specification of Letters Patent.

Patented Get. 31, 1916.

Application filed March 8, 1916. Serial No. 82,978.

To all whom it may concern Be it known that I, CrmRLn-s A. GoINs, acitizen of the United States, residing at Tulsa, in the county of Tulsa,State of Oklahoma, have invented a new and useful Wagon-Spring, of whichthe following is a specification.

The object of this invention is to provide a wagon spring that may bereadily attached or detached to the ordinary bolster, so that the wagonbody may be. used with or without the springs and so that, in caseswhere it is desired to utilize the wagon truck without the body thesprings may be readily detached and the bolsters will. then be free forany of the conventional uses.

A further object of this invention is to construct a wagon spring of aplurality of spring units of variable tension, each of the units beingindependent and interchangeable.

A still further object is to provide a spring of this type not only withunits of variable tension but wherein the independent elements areconstructed so as to have a graduated tension.

With these and other objects in view, reference will be had toaccompanying drawings, forming a part of this specification, and whereinlike characters of reference designate corresponding parts throughoutthe several views, in which Figure 1 is a fragmentary perspective of thespring carrying element showing one of the springs in position. Fig. 2is a front view of one of the bolsters showing the spring in position.Fig. 3 is a fragmentary perspective showing another form of catch, andFig. t is a perspective of a portion of the base of one of the springsshowing the locking rod in dotted lines.

Reference character 1 indicates a bolster upon which is seated a springcarrying member in the form of a beam or bar of rectangular crosssection, indicated by 2. This bar or member 2 is secured in position onthe bolster by means of U-shaped clips 3 which seat in and engage thegrooves i. The king pin 5 is in this instance shown passing through thespring carrying member, however this feature is immaterial as the clipsform a satisfactory fastening means.

The spring carrying member is provided with cups or pockets 6 to receivethe springs. These pockets 6 are formed in the top of the member 2 andare spaced in a relative predetermined manner according to the type andtension of the springs used. These pockets are of sufficient depth tosecurely pocket the ends of the springs and one of the walls of each ofthe pockets adjacent to one of the longitudinal edges of the said springcarrying member 2 is cut away to form a passage or opening to allow theplacing or removing of one of the springs from the side. The bottom ofthe pocket may have an inwardly inclined face as shown at 6 to cause amore effectual seating of the spring. Such a provision is not necessarybecause of the fastening means provided.

The fastening means may be in the form of a longitudinal. rod 7 whichextends through the carrying member 2 in such a manner as to engage oneof the coils of the springs, which latter may or may not be providedwith a depression for the seating of same.

The springs are preferably of coiled formation and the thickness andstrength ofeach of the springs gradually decreases from the base upward,so that resistance against depression gradually increases. The springsare of varied length and tension, the longer springs 9, 9 being locatednear the extremities of the spring carrying member 2, and theintermediate springs, which may be of any suitable number, are of everincreasing tension and decreasing length as they approach the centralspring 10. This latter being of greater strength acts not only as aspring but as a buffer or stop for the wagon body when the other springshave been depressed to their limit. In the present instance there areshown seven springs, including the central or buffer spring 10. Aspreviously stated the other springs gradually increase in lengthoutwardly and tension inwardly, the two springs next adjacent the bufferspring being of equal height and tension, etc., and each of the othersets of corresponding springs on the opposite sides of the buffer springbeing approximately equivalents.

In use it will be seen from Fig. 2 that the wagon body indicated by thereference character A normally rests on the longer springs 9, 9 whichare secured near the ends of the spring carrying member. When additionalweight is placed in the Wagon body these springs will be depreessed andthe body will engage and rest upon the second set of s rin s and thismovement of the P a: V

' wagon body due to increased weight will the bar 2 continue untilfinally the body will rest upon the central spring 10 which is of suchexcessive tension as to act as a buffer and to prethis latch 12 is ofresilient material to enable more convenient disengagement from thecatch 14:.

Various changes may be made in the details of construction andarrangement with out departing from the spirit of the invention. V V\Vhat I claim as new and useful and desire to secure by Letters Patent,is

1. In a device of thecharacter described comprising a bar springsmounted on said bar, one of the springs being located approximately thelongitudinal center the said bar, the remainder of said springs beingarranged in pairs, each of the springs of each pair being located onopposite sides of said central spring and each pair of said springsbeing of equal size and similar tension the size of said springs beinggradually increased toward the extremities and the tension of saidsprings being gradually increased toward the center of said springcarrying bar, and fastening means for said springs.

2. In a device of the character described comprising a bar, pocketsformed in said bar, springs mounted in said pockets, the bottom of saidpockets having inwardly inclined faces for the reception of the base ofsprings one of the walls of each of said pockets adjacent one of thelongtiudinal edges of said bar being cut away to allow the placing andremoval of said springs, one of said springs being located approximatelythe longitudinal center the said bar, the remainder of said springsbeing arranged in pairs, each of the springs of each pair being locatedon opposite sides of said central spring, and each pair of said springsbeing of equal size and similar tension, the size of said springs beinggradually increased toward the extremities and the tension of saidsprings being gradually increased toward the center of said bar, andmeans for locking said springs in position comprising a rod extendinglongitudinally through said bar and engaging same.
